  • the present invention relates to a work vehicle in which a cooling system has a coolant fluid radiator, and a cooling unit adjacent to and facing the coolant fluid radiator.
  • a second radiator is movably attached to a first radiator via a first connector and a second connector.
  • the first connector is a swing link mechanism having a slide mechanism and connects upper portions of the first radiator and the second radiator.
  • the second connector is a slide mechanism and connects lower portions of the second radiator and the second radiator.
  • the upper portion of the second radiator can be significantly separated from the upper portion of the first radiator by swing displacement and slide displacement, and the lower portion of the second radiator can be slightly separated from the bottom portion of the first radiator by slide displacement.
  • a hand may be inserted between the first radiator and the second radiator.
  • such a cooling system requires a swing link mechanism having a slide mechanism and a slide mechanism in order to attach the second radiator to the first radiator, and such an attachment structure is complicated and occupies a large space.
  • a slide mechanism having a long hole and pin in particular, not only increases manufacturing costs but has the disadvantage of foreign materials easily lodging in the long hole.
  • the present invention provides a technology in which a space for maintenance/inspection purposes is easily created between a coolant fluid radiator and a cooling unit configuring a cooling system for work vehicles.
  • a working vehicle has a vehicle body frame, an engine mounted to the vehicle body frame, a cooling fan unit provided in one direction of an anteroposterior direction of the vehicle body with respect to the engine, a coolant fluid radiator provided on the opposite side of the cooling fan unit with respect to the engine, a cooling unit provided on the opposite side of the coolant fluid radiator with respect to the cooling fan unit, and a link mechanism connecting the coolant fluid radiator and the cooling unit such that a distance between the cooling unit and the coolant fluid radiator in the anteroposterior direction of the vehicle body can be changed.
  • the link mechanism is configured as a four-link mechanism having a left/right pair of upper links and a left/right pair of lower links.
  • the cooling unit is swingably supported by the coolant fluid radiator.
  • the cooling unit By swinging the cooling unit using the four-link mechanism, a space is formed between the coolant fluid radiator and the cooling unit, thereby facilitating maintenance/inspection of cooling surfaces thereof.
  • the four-link mechanism is simple in structure and low in manufacturing costs.
  • the cooling unit includes a first cooler provided in an upper half area of the coolant fluid radiator and a second cooler provided in a lower half area of the coolant fluid radiator.
  • the first cooler is connected to the coolant fluid radiator via the link mechanism, and a bottom end of the first cooler and an upper end of the second cooler are connected via a connecting unit.
  • the first cooler and the second cooler are provided facing opposite a cooling surface of the coolant fluid radiator having favorable circulation of cooling air, and cooling air can pass through the two types of coolers in an efficient manner.
  • the connecting unit when a swinging connection unit, which swingably conncects the first cooler and the second cooler about a swing axis in a transverse direction of the vehicle body, is adopted as the connecting unit, the second cooler is able to maintain an upright posture despite an inclined posture of the first cooler.
  • the second cooler has an inclined posture in tandem with the first cooler, the bottom end of the second cooler is significantly separated from the coolant fluid radiator, leading to a swing space of the second cooler becoming too large.
  • the swingable connection of the first cooler and the second cooler resolves this.
  • the third cooler is preferably provided on the opposite side of the second cooler with respect to the coolant fluid radiator, and is preferably connected to the bottom end of the first cooler.
  • the third cooler is provided across from the coolant fluid radiator with the second cooler in between. That is, the cooling surface of the coolant fluid radiator and a first cooling surface of the second cooler, and a second cooling surface of the second cooler and an inner cooling surface of the third cooler are nearly parallel and positioned in immediate proximity to one another.
  • the third cooler has a similar inclined posture following along an extension from the first cooler.
  • the second cooler maintains an upright posture, and thus a space is formed in between the cooling surface of the coolant fluid radiator and the first cooling surface of the second cooler, and the second cooling surface of the second cooler and the inner cooling surface of the third cooler, thereby facilitating maintenance/inspection.
  • a length between each support point of the upper links and the lower links on the coolant fluid radiator side is preferably shorter than a length between each support point of the upper links and the lower links on the cooling unit side, and a length between the support points of the upper links on the coolant fluid radiator side and the support points on the cooling unit side is preferably shorter than a length between the support points of the lower links on the coolant fluid radiator side and the support points on the cooling unit side. Further, by making the length between each support point of the lower links and the upper links on the coolant fluid radiator side shorter than the length between each support point of the lower links and the upper links on the cooling unit side, an efficient use of space and ease of maintenance/inspection is achieved.
